Millions of people across Spain, Portugal, and southern France mostly Europe Blackout on Monday. The blackout caused big problems:
- Traffic lights stopped working
- ATMs shut down
- Phones went offline
- Trains and elevators got stuck
- People ate dinner by candlelight
Spain’s Prime Minister, Pedro Sánchez, said the exact cause is still unknown. Early reports in Portugal blamed a rare event called “induced atmospheric vibration.” That report was later corrected, but what does this term really mean?
Can Weather Cause Blackouts?
Yes. In the U.S., 83% of blackouts from 2000 to 2021 were due to weather. Here's how weather affects power:
- Storms knock down power lines
- Heatwaves overload the grid
- Fires destroy power stations
- Wind causes power lines to shake
This shaking is called vibration. It can be:
- Conductor galloping (big, slow waves)
- Aeolian vibration (small, fast waves)
These movements can break equipment and cause blackouts. Engineers use special tools called stock bridge dampers to reduce these vibrations.
What Is ‘Induced Atmospheric Vibration’?
This is not a common scientific term. But it likely refers to a real effect.
When the weather changes fast—like during heatwaves or storms—the air pressure shifts quickly. This can create waves in the atmosphere, like ripples in water. These waves can hit high-voltage power lines and make them shake.
These waves are known as:
- Gravity waves
- Thermal oscillations
- Acoustic-gravity waves
The risk comes not just from high heat, but how fast and unevenly temperatures change. This may cause problems in big power systems.
Are Power Grids Too Centralized?
Yes. Our power systems today are large and connected across big areas. That makes them more vulnerable to:
- Weather changes
- Equipment stress
- Growing demand from electric cars and devices
One small issue can cause a big blackout.
What's the Solution?
Experts suggest we move toward local microgrids. These are small, flexible power systems that:
- Serve one area or community
- Can run alone during a big outage
- Are more resilient and stable
This helps reduce the risk of large blackouts.
Final Thoughts
Whether or not “induced atmospheric vibration” caused the blackout, one thing is clear: Our power grids are too fragile.
To protect our energy future, we must build systems that are:
- Local
- Smart
- Ready for climate change
